Specification of Letters Patent.

LAST.

Patented Nov. 15, 191i).

Application filed December 11, 1908. Serial No. 466,945.

To all whom it may concern:

Be it known that I, F nnnnnron WY. Mn.- LAY, of Haverhill, county ofEssex, State of Massachusetts, have invented an Improve- I subsequentlyinserted in the hole which has been bored, which projects beyond themain portion of the last, so as to engage the block and act as a stop tohold the same from being pushed toward the toe beyond the point at whichit is desired that it be held. In lasts of this character, the insertedwooden pin, above referred to, is a source of much difficulty, for,while this pin is tightly fitted and glued in place, it often becomesloose from various causes, so that the pressure of the block against itcauses its lower end to protrude beyond the bottom of the last, or thepressure on the last bottom causes the pin to be depressed, with theresult that injury is frequently caused to the bottom of the shoe, or,at least, an indentation is formed on the sole, during the beating outprocess, which may be removed only with difiiculty, if at all. For this,and other reasons, such as failure to withstand transverse strain,renewal of these pins is often required.

The object of my invention is to provide a form of last block holdingpin which is adapted to be readily applied to the last, which will notbe forced through the bottom of the last by the action of the last blockthereon, and which will be securely held in place, so that renewal ofthe pin will seldom, if ever, be necessary, but may be readilyaccomplished if necessary. I accomplish this object by the means shownin the accompanying drawing, in which,

Figure 1 is a plan View of a last provided with my invention, andshowing the last block removed. Fig. 2 is a sectional view on the line2-2 of Fig. 1, showing the last block in position. Figs. 3 and 4: aredetail views showing different steps in the process i i I of preparingthe last to receive the last block pin.

As shown in the drawing, the main body a of the last and its block b,and spring-locking pin 0, are of ordinary form, the plane of severanceof the last block curving upwardly at its lower or front end.

According to my invention, I provide a metal holding pin (Z for thefront end of the block, said pin being of cylindrical form and having atapering screw threaded extension 6, at one end, of much smallerdiameter, and approximately half the length thereof. The upper end ofsaid pin (Z is provided with a slot (Z adapted to receive an ordinaryscrew-driver. In preparing the last to receive said pin, a hole f ofsmall diameter is bored through the bottom of the last up into its blockportion, as indicated in Fig. 3, and the block is then sawed from themain body portion on the plane of severance indicated. The hole f in theblock is then counterbored to the end thereof, and said hole is alsocounterbored in the main portion of the last from the side at which theblock is removed for a portion of its thickness, forming abore g, asshown in Fig. i, and a shoulder h at the end of the counterbore. Thefront side of the bore in the block is cut away, as indicated at 2', tothe end of the block, as is customary. The pin cl is then inserted inthe bore 9, and its extension 6 screwed into the bore f, until the innerend of the pin firmly engages the seat It and the outer end thereofprotrudes to an extent sufficient to engage the block. The diameter ofthe bore 9 and the pin d are the same, so that said pin will fit closelytherein, the remaining portion of the bore f being of a size to permitthe extension 6 to be tightly screwed'therein, so that the pin is thusfirmly fixed in the last, and, as said extension is somewhat taperingthroughout its length and is of approximately the diameter of the smallbore at its extreme end a seat for nearly the entire end of the plug isprovided. The end of the threaded extension 6 terminates a shortdistance above the bottom of the last, and the diameter of the bore f isso small that there is no necessity of filling it after the pin has beeninserted.

With the above described construction, the block-holding pin will befirmly held in position against all strain transversely, and, as the pinalso seats firmly against a shoul- Q mps der in the counterbore, saidpin will not be forced outwardly through the bottom of the last by theoblique pressure of the block against it.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is A last comprising the main body portion andits block, said body portion having an aperture extending therethroughbeneath the front portion of the block, the diameter of the lowerportion of said aperture being materially less than that of the upperportion to provide a shoulder therebetween, and a metal block-holdingpin tightly fitted in the portion of said aperture of larger diameter,seating at its lower end against said shoulder, and having at its lowerend a threaded extension screwed into said aperture of small diameter,the opposite end of said pin protruding to engage the block,substantially as described.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
